Increasing research and development into new forms of renewable energy are MOST important because

1 answer:

5 0

The correct answer is B) people like saving the planet.
Because of the usage of fossil oil and coal extensively in the last few hundred years the Earth and the environment are suffering very badly, this of course affects the humans, their health and life in total. It is obvious that if this trend continues we will make the planet unrecognizable and destroy big portion of it, which will make us suffer or die out as well, so people have been trying to develop renewable energy as much as possible for both the planet's and their own well being, but also are trying to make it as cheep as possible so that it is economically not damaging.

What is the value of X6? Show the solution.

wariber [46]

Answer : The value of $x_6$ is $\sqrt{7}$ .

Explanation :

As we are given 6 right angled triangle in the given figure.

First we have to calculate the value of $x_1$ .

Using Pythagoras theorem in triangle 1 :

$(Hypotenuse)^2=(Perpendicular)^2+(Base)^2$

$(x_1)^2=(1)^2+(1)^2$

$x_1=\sqrt{(1)^2+(1)^2}$

$x_1=\sqrt{2}$

Now we have to calculate the value of $x_2$ .

Using Pythagoras theorem in triangle 2 :

$(Hypotenuse)^2=(Perpendicular)^2+(Base)^2$

$(x_2)^2=(1)^2+(X_1)^2$

$(x_2)^2=(1)^2+(\sqrt{2})^2$

$x_2=\sqrt{(1)^2+(\sqrt{2})^2}$

$x_2=\sqrt{3}$

Now we have to calculate the value of $x_3$ .

Using Pythagoras theorem in triangle 3 :

$(Hypotenuse)^2=(Perpendicular)^2+(Base)^2$

$(x_3)^2=(1)^2+(X_2)^2$

$(x_3)^2=(1)^2+(\sqrt{3})^2$

$x_3=\sqrt{(1)^2+(\sqrt{3})^2}$

$x_3=\sqrt{4}$

Now we have to calculate the value of $x_4$ .

Using Pythagoras theorem in triangle 4 :

$(Hypotenuse)^2=(Perpendicular)^2+(Base)^2$

$(x_4)^2=(1)^2+(X_3)^2$

$(x_4)^2=(1)^2+(\sqrt{4})^2$

$x_4=\sqrt{(1)^2+(\sqrt{4})^2}$

$x_4=\sqrt{5}$

Now we have to calculate the value of $x_5$ .

Using Pythagoras theorem in triangle 5 :

$(Hypotenuse)^2=(Perpendicular)^2+(Base)^2$

$(x_5)^2=(1)^2+(X_4)^2$

$(x_5)^2=(1)^2+(\sqrt{5})^2$

$x_5=\sqrt{(1)^2+(\sqrt{5})^2}$

$x_5=\sqrt{6}$

Now we have to calculate the value of $x_6$ .

Using Pythagoras theorem in triangle 6 :

$(Hypotenuse)^2=(Perpendicular)^2+(Base)^2$

$(x_6)^2=(1)^2+(X_5)^2$

$(x_6)^2=(1)^2+(\sqrt{6})^2$

$x_6=\sqrt{(1)^2+(\sqrt{6})^2}$

$x_6=\sqrt{7}$

Therefore, the value of $x_6$ is $\sqrt{7}$ .

The ____ have dense network of road

mariarad [96]

Answer:

plains

Explanation:

It has been noted that the density of road infrastructure is higher in the plains.

This is because the terrain is leveled and easier for building, which makes it more likely for cities and settlements to be built here. If the population of the region is higher, there is more need for the roads and traffic to be built.

Additionally, it is easier to drive through the plains than to through the mountains, which is why roads will be built in the plains more likely. When the terrain is leveled, roads can also be built through the forests and deserts.

The question 5.9, what is the correct answer?

Gnoma [55]

Answer:

Japan and South korea were forced to industrialize because they lacked B. Arable land

Explanation:

Japan and South Korea separates by the Korea Strait in Pacific Ocean. Japan start to industrialise from late 19th century and capture the Korean country through Sino Japanese war. Imperialism and Industrialisation are two sides of the same coin, because industrialisation need Land, Labour and capital. Both countries lack in Arable land, Japan performs agriculture in Ship and terrace of building, it is in temperate region latitude. Apart from land, labour is much hardworkers in both the country. Japan is island nation so petroleum products are easily extracted and South Korea is Peninsular country their petroleum products are extracted from shoreline. Both countries are top position in economic growth.
